Question

I have a test tomorrow. please tell me how Fleming right handrule Is applied here. I will mark the answer brainlest

Answer 1

Here, we see a diagram of an electric generator. An armature is placed in the middle of magnetic field. The armature is rotated with mechanical force. As the armature rotates in the magnetic field there is electricity produced in it. According to Fleming's right hand rule :-

Thumb shows motion of conductor

Pointer finer shows directio nof magnetic field

Middle finger shows direction of induced current.

Armature is connected to slip rings which help in reversing direction of current by slightly touching the carbon brushes.

Using right hand thumb rule we can find the direction of induced current here. Interestingly, the current here is AC which changes its direction because of slip rings as when the direction of force changes, the direction of current changes too.

Hope that helps you. Tried my best to explain it. I recommend you to reasearch and self study on this topic. It took me a while to understand it too !
